Warranty for a visor? That is one warranty worth voiding I'd say, if it is worth anything to begin with.
Anyways, the only thing that worked for me was a mask isolating my nose and mouth completely from the rest of the helmet. Shoei makes them, I took the larger one. Now I can breathe as hard as I want and it doesn't affect the visor.
Of course that doesn't help against fogging completely, so I also have a Pinlock, which in turn is almost useless on its own when we have our typical Autumn / Winter weather here. The combination of the two does the trick.
Almost. I now added Cat Crap to the Pinlock insert and the visor, and it seems to help a little, just enough.
